Application led February 4, 1918. Serial No. 746,218.

To all 'whom it may concern Be it known that I, SAMUEL Tnoon, a citizen of the United States, and a resident of Edgewood Park, .in the county kof Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Curling- Irons, of which the following is a specification.

My invention relates to electrical heating devices, and it has special reference to electrically-heated curling irons.

The object of my invention is to provide a curling iron embodying a resiliently vsupported heater element for preventing breakage, and a swiveling attachment whereby above-mentloned objectionable features' are' removed by reason of a swiveling concentrically-disposed plug-and-socket connector and a resiliently-supported heater element, as hereinafter described.

In the accompanying drawing, Figure 1 is a view, partially in longitudinal section and partially in elevation, with parts broken away, of a curling iron embodying my invention; Fig. 2 is an enlarged longitudinal section, with parts broken away, of the plugconnector and the heater embodied in my invention; Fig. 3V is a View, in' elevation, of the socket port1on of the connector shown 1n Fig. 1; Flg. 4 is a view, 1n section, on the line IV-IV of Fig. 1; and Figs. 5 and 6 are views, in section, taken 'similarly on the lines V'-V and VI'-VI, respectively.`

Referring to the drawing, a curling iron 1 comprises a heater 2, a cylindrical shell 3 incasing the heater 2, a pivotally mounted tong 4 litting over the shell 3, a handley 5 supporting. one end of said shell', an auxiliary handle member 6, and a plug-and-socket connector 7 disposed` within thehandle 5.

The heater 2 comprises a centrally dis- Specication of Letters Patent.

posed \rod 8, a layer of suitable insulating material 9 disposed around said rod, a plurality of convolutions of conductor 10 wound around the `material 9, and an outer'protectlve covering 11. It is understood that said conductor may be embedded in cement, in which case no covering is necessary. The incasing shell 3 fits within a ferrule 12 on the handle 5 and is provided with a button is well-known in the art and conse uently need not be further described. The(l1andle 5 comprises a main body portion 14..A and a thin-walled shell 15 projecting beyond' the outer end of said body Jportion and adapted to'contain the plug-and-socket connector 7, as hereinafter described.l An axially-disposed recess 16 extends through the bod portion 14 and is lined with a.- metal-.Shel 17. The rod8 is connected to one end of the heater conductor 10 and extends within the hollow shell 15 for formingv one terminal member 18, which is provided with a cupped l end 20. A second terminal member 19 consists of a tube insulated from and concentrically disposed around the rod 8 near its free end. The said tube has a bulb-shaped end 22 that is adapted tofengage a tubular clip 25, as hereinafter described. (See Fig. 2. f f he auxiliary handle member 6 is of insulating material and tubular in form, and comprises two portions, an outer-portion 6, adapted to be held i the hand and into which supply conductors 23 and 24 extend, 90

' and a portion 6b, which screws into the portion 6a and is adapted to fit loosely within the shell 15 ofthe 'handle 5, and acts as'a guiding member for the connector 7.

The terminals 18 and 19 comprise the plug` portion of the connector 7, and the main socket portion vcomprises a tubular clip 25, of substantially bottle-shape, provided'with a plurality of longitudinalv slots 26-to lend resiliencythereto. A ring 27 is attached to the unslotted end of the clip 25 and has an, integral arm 28 to which the supplyconductor 23 is connected b a. screw 29. A centrally disposed rod 30 isrigidly supportedand insulated from the ring 27 by insulatingdisks 31 and engages the cupped I end20 of the terminal 18. A metal strip 32 serves to connect the outer end of the rod screw 33.

' A spring 3d is .disposed at the outer end oit the incasing shell 3 upon the button 1 3 to cooperate with the clip, to resilientlyv support theheater element 2, thus relieving the thrust lining the recess 16 in the handle 5, acts as a resilient guide tor the terminals 18 and 19 by reason ot having a plurality of ngers A cut from the Wallsnear lthe outer endl and bent inwardly to engage member 19.

The adaptability of the curling iron to rotative movement with respect to the auxiliary handle member 6 will be understood from the foregoing description.

llnusing the curling iron, the auxiliary handle member 6 may beheld stationary,

the terminalv and the iron turnedbetvveen the thumb and forenger, thus facilitating the process of hair-curling. During the rotative movement, the bulb-shaped endof the terminal 19 may turn Within the clip25, and the rod 30 may turn Within the cupped end 20 of 'the terminal 18, thereby keeping the elec? ytrical circuit intact. l

li do not Wish to be restricted to the speciic structure and details herein set forth, but desire that only such limitations shall be imposed as are indicated in the appended claims.
